Abstract

Shaped zirconia particles are prepared by mixing zirconia powder with an aqueous colloidal zirconia solution or an aqueous acid solution so as to obtain a shapable mixture containing about 4-40 weight-% water, shaping this mixture, and heating the shaped particles at a temperature in excess of about 90 DEG C.
